Since its publication in 1902, John Grier Hibben's classic work on Hegel'sEncyclopediaLogic has been one of the clearest, most illuminating, mosthelpful, and most popularexpositions of this rich and difficult text. Nevertheless,its language has needed to bemodernized, its interpretations have needed to berevised and updated in view of recentHegel scholarship, and its findings haveneeded to be related to a wider context in thehistory of philosophy. Writing asHibben's co-author, Eric v.d. Luft has done all thisand more, adding twochapters and an annotated bibliography, expanding the glossary,providing exactcitations, keying the commentary directly to Hegel's section numbers,supplyingillustrations and examples, and strengthening the arguments. The result isanexcellent supplementary text for 21st-century students and Hegel scholars.
